My invention relates tov metallic lshingles. for roofing and like purposes.

Important objects of my invention are interchangeability and to secure interlocking of the shingles.

Further objects are to enable automatic or facilelocating of the shingles each other during the laying operation; to present an appearance approximately resembling that of a wooden shingle; to enable the use of a minimum of material; to insure an interlocking engagement of the interengaging shingles in such a manner as to insure against relativemovement bothlaterally and longitudinally; to 'prevent penetration of water through both the joints and through the nail holes; and to attain these ends in a strong and inexpensive structure.

To the above ends essentially m invention consists in such parts and in suc combinations of parts as fall within the scope 'of tlie appended claims.

My'shingle com rises an oblong body 10 of metal such as t in pressed vsteel cut and bent up by suitable tools from a flat blank to form a forwardly inclined rectangular housing portion 11 extending longitudinally from intermediate the length of the body to its lower end, and laterally s aced from the side edges `oi the body. The ront wall 12 of the housing terminates in a rearwardly directed end wall 13 disposed in an acute angle to the housing wall 12, and at a right angle 50 to the body portion 10 of the shingle, and has relatively to .inwardly and upwardly to resultant rearwardly directed angular or tapering lateral walls 15 and 16. The latter wall is of slightly less depth than the former, so that the adjacent marginal strip or portion 17 ofthe body 10 is slightly higher than 56 the opposite marginal body strip or portion 18 which is substantially in the plane of the rear edge of the wall 13. An outwardly directed peripherally angular fiange 20 upon the lower lateral edge of the portion 18 of 60 the body has its forward edge 21 ta ering correspond) with the inclination of the housing wall 12, and its lower edge 22, disposed at an acute angle to its forward edge, and is parallel with the housing side wall 15, forming in conjunction therewith, and with the body portion 18, a longitudinal transversely rectangular channel 23.

Immediately above the housing portion 11 70 are longitudinally disposed raised marginal' ribs 24 having their outer edges in substantial alignment 4with the walls 15 and 16 or slightly inset therefrom. Similar raised ribs 26, two in number, parallel with the first ribs, and in transverse alignment therewith, are located between the latter and equally spaced therefrom. The ribs 26 are spacedv from each other a distancev approximately or slightly greater than the width of the channel 23, the thickness of the wall 15, and of the flange 20.

A second horizontal series of'longitudinally disposed raised ribs are formed in the body l0 as far above the lower ends of the first 85 series as the lower ends of the first series are above the lower end of. the housing portion, and are of the same length as the ribs of the first series. The second series comprises ribs 27 in vertical alignment with ribs 24, and 90 ribs 30 in vertical alignment with the ribs 26.

Midway between the ribs 24 and 26, and midway between the ribs 27 and 30, are raised or hollow conical or tubular studs 32 provided with nail holes 33 in their apices.

In ylaying the shingles those of the same course successively overlap laterally throughout their lengths so that each mar inal strip 17 rests upon and covers part of tliestrip 18 of the next shingle, and its free lateral edge 10 snugly contacts with the exterior of the adjacent housing wall '15, ,while the housing wall 16,'with which it is integral, coincides locked, but resultant exposed gutters 35 are formed for the escape of the water, and the `water is prevented from penetrating to the roof while passing through the gutters because the tightly seated strip 17 prevents the moisture reaclung even the stri 18 below. Since the lower ed e 21 of eac flange 20 abuts against the en wall 13 of the enclosing housing portion of the laterally adjacent righthand shingle, one corner of the latter is locked against excessive upward longitudinaly movement during and after the laying operation. n The right hand shingle is further located and checked against excessive upward movement during and after laying, by reason of the abutment of the lower ends of the lowermost series of ribs 24 and 26 against the housing wall 13. The laying of the described course of shingles is, because of their described structure such that the shin les are self-aligning, since the locating an interlocking of the right shingle relatively to the already laid left hand shingle is eifected by a single movement to the right and upwardly. The shingles are attached to the roof or other backing by nails driven through the openings 33 in the tubular studs 32 at suitable intervals duringthe shingling operation. The studs enclose the upper portionsof the nail Shanks and prevent'access of water to the elevated nail holes 33.

The next upper course of shingles are laid from left to right with the individual shingles overlapping and in staggered relation to the next lower course, as shown in Figure 5. It will be observed that the upwardly pressed ribs of the upper row of lower shingles enter the concave portions of the lower row ofthe ribs of the shingles of course next above, and thus not only assist in locating the shingles 'as they are applied but still further strengthen interengagement. y It will I be further noted that the pairs of central ribs 26 and 30 of the lower shingle embrace between them the walls of the gutters or troughs 35- formed in the shingles of the next upper course at their jointed ortions, as is evident from an'inspection of igure 8. This feature is an additional interlocking element. Locating and locking is further assisted by the registration of the studs 32 of a lower course in the concave portions of the studs in the next higher course 33.

The fact that there are no portions of the shingle extending laterally therefrom, and its gradually increased thickness at its bottom portion, aords the shingle a perfect oblong outline in perfect imitation of thel wooden shingle whichis a desideratum in this art.

This construction also avoids the necessity of independent .or auxiliary means forattaching the shingles to the roof.

Having thus described one illustrative embodiment of my invention it is to be understood that the specific terms employed are used in a descriptive sense only, and are not for the purpose of limitation, the scope of the invention being defined by the scope of the appended claims.

I claim `1. A metal shingle comprising an oblong body portion, a longitudinal housing portion inset from both later-al edges of the body portion and extending from a point'intervmediate the length of the latter to-the lower end thereof comprising an inclined front wall, an inwardly directed butt edge wall and inwardly directed side walls, one o said walls extending to the-plane of the rear edge of the end wall, and the other of the side walls being of less de th, and an outwardly directed angular ange upon one side edge of the body portion adjacentthe deeper side housing wall and parallel therewith including an outward edge longitudinally inclined to conform with the inclination of the front housing wall.

2. A metal shingle comprising a body portion, a longitudinal housing ortion inset from both lateral edges of the ody portion and extending from a point intermediate the length of the latter to the lower ed e thereof comprising an inclined front wa l, an inwardly directed butt edge wall, inwardly di-y rected side walls, an outwardly directed angular flange upon one side edgeof the body portion parallel with the side walls of the housing, and longitudinally disposed raised vmarginal ribs in the body portion above the housing comprising portions in substantial alignment with the slde housing walls.

3. A metal shingle comprising a body portion, a longitudinal housin pjortion inset from both lateral edges of t e ody portion and extending from a point intermediate the length of the latter to the lower vend thereof comprising an inclined front wall, an inwardly directed butt edge wall, inwardly directed side walls, an outwardly directed angular flange upon one side edge of the body ortion parallel with the side walls o f the 4. A metal shingle comprising a body portion, a longitudinal housing ortion inset from both lateral edges of the Itliody portion and extending from a point intermediate the length of the latter to the lower end thereof comprising an inclined front wall, an inwardly dlrected butt edge wall, inward- 1y directed side walls, an outwardly directed angular iiange upon one side edge of the body portion parallel with the side walls of the housing, a horizontal row of longitudinally disposed raised ribs in the body immediately above the housing, and a second row of similarly disposed raised ribs disposed in the body intermediate its upper end and the first row.
